IMPROVEMENT IN SAW-JACK.

The Schedule V.referred to in these Letters P atent and making `pari: of the same To all twhom it may concern:

Be it known 'that I, ABEL WHITLOCK, of Danbury, in the county Fairfield, in the State of' Connecticut, have invented a new and improved Saw-Jack; and I do hereby declare that the followingv is a full and exact description thereof, reference beingr had to the accompanying drawings and to marked thereon.

lhe nature ot' my invention consists in the structure and operation of the socket-arms, which receive and hold the stick to he sawed, adjusting their greater separation to support longer sticks by swerving on pivotsoutward, and their lesser separation by s'werving inward. y,

On the branches of the socket-arms I attach gripes, which hold thestick firmly when placed in and heilig sawed, which gripes are caused `to act by the -stick when being placed in and to retain their gripe hy the weightv ofthe stick, the adjustment being elected easily, and the stick to be sawed being held rmly.

To enable others skilledl in the art to make and use my inventiomI will proceed to describe its construction and operation. e

I construct my saw-jack ot' cast iron, but wood, or

wood and iron, may be used. I make the lower part or foot ofthe jack with legs, anda plate attached t0 the letters of reference Vthe legs, which plate sustains the socket-arms, at-

tached to it by pivots, on which they turn, when the socket-arms are adjusted to shorter or longer distances by swerving inward or outward to sustain longer or shorter sticks to be sawed. Y

The socket-arms branch out in Convenient form to receive sticks placed in them to' be sawed. On each of these branches are gripes, attached by pivots, on which they turn.

llhe gripes open when the stick is taken out and close when the stick is placed in, the weight of' the stick-causing the gripes to hold the stick firmly.

Saw-jacks adjusted by the sliding imode usually are inconvenient and unsteady, an`d they are ina-dequate to hold the stick firmly.

` Figure-l is a view of the saw-jack.

Letters A B C exhibit the part-s. f

That I eiaimas my invention, and desire to secure by Letters Patent, is

The saw-jack herein described, when constructed and operated substantially as and for the purpose set forth.
